Global Use of Renewable Energy Sources

The contribution of renewable energy sources to the global primary energy supply was 13.5 per cent in 2001 (IEA, 2003b). Biomass is the most important renewable energy source today and has a share of 80 per cent among the renewables. Only three centuries ago, renewable energy sources provided virtually the entire global energy supply and many studies show that this might be achieved again in the future. However, other renewable energy sources such as solar power and wind power will be crucial in the future. This section shows the installed capacity and the growth rates of recent years for different renewable energy sources, starting with the electricity supply where renewables provided about 18 per cent of the global demand in 2001.
